Unlike Korean massage parlors, Chinese massage parlors, and like Latin massage parlors, and Russian massage parlors, American massage parlors are very often owned and operated by men. In the case of American MPs however, the men often play an active role in running the business. While you may find a man behind the scenes of a Chinese MP, he will usually stay under-the-radar. In my experience most Korean MPs are owned and operated by women, even when men have provided funding.
Often the American men get into trouble, as their bravado, edo, and sexual drive get them into trouble. Many times they brag about their money and their opportunity with the ladies, and the out in the open bragging never leads to anything good.
There were reports a while back about stock brokers running massage parlors in absentia, using the business as a quick means of raising pocket cash and getting access to quick carnal favors. I believe it was even written up in Forbes magazine at one time.
While the American massage parlor may be the best place to find blonde, girl next door style massagers, it is often the more high-profile, aggressive establishement when compared to AMPs, RMPs, and LMPs.
